Description
FileSystem.getFileCacheHints via DFSClient.getHints (post HADOOP-894?) returns IP address of the datanodes instead of the hostnames which breaks mapping from task-tracker to datanodes in map-reduce i.e. the system cannot intelligently place maps on datanodes where blocks are present.
I have verified that this affects trunk only, branch-0.13.0 seems ok.
